摘要：The coordination of supply chains by means of contracting mechanisms has been extensively explored theoretically but not tested empirically. We investigate the performance of three commonly studied supply chain contracting mechanisms: the wholesale price contract, the buyback contract, and the revenue-sharing contract. The simplified setting we consider utilizes a two-echelon supply chain in which the retailer faces the newsvendor problem, the supplier has no capacity constraints, and delivery...

摘要：We propose that ambiguity aversion, as introduced in the literature on decision making under uncertainty, drives a preference for established brands in multiattribute choices among branded alternatives. Established brands are those for which belief in quality is held with greater confidence, even if specific attributes might be inferior to those of competing, less-established brands. In five experiments, we examine the role of ambiguity aversion in the preference for dominated, established bra...

摘要：Estimating quantile sensitivities is important in many optimization applications, from hedging in financial engineering to service-level constraints in inventory control to more general chance constraints in stochastic programming. Recently, Hong (Hong, L. J. 2009. Estimating quantile sensitivities. Oper. Res. 57 118-130) derived a batched infinitesimal perturbation analysis estimator for quantile sensitivities, and Liu and Hong (Liu, G., L. J. Hong. 2009. Kernel estimation of quantile sensiti...

摘要：Since Osborn's Applied Imagination book in 1953 (Osborn, A. F. 1953. Applied Imagination: Principles and Procedures of Creative Thinking. Charles Scribner's Sons, New York), the effectiveness of brainstorming has been widely debated. While some researchers and practitioners consider it the standard idea generation and problem-solving method in organizations, part of the social science literature has argued in favor of nominal groups, i.e., the same number of individuals generating solutions in...

摘要：State-of-the-art stochastic volatility models generate a volatility smirk that explains why out-of-the-money index puts have high prices relative to the Black-Scholes benchmark. These models also adequately explain how the volatility smirk moves up and down in response to changes in risk. However, the data indicate that the slope and the level of the smirk fluctuate largely independently. Although single-factor stochastic volatility models can capture the slope of the smirk, they cannot explai...

摘要：Strategic models of auditor-inspectee interaction have neglected implementation details in multiple-inspectee settings. With multiple inspectees, the target audit probability derived from the standard analysis can be implemented with sampling plans differing in the budgets committed to support them. Overly committed audit budgets tie up unneeded resources that could have been allocated for better uses. This paper studies the minimum committed budget required to implement a target audit probabi...

摘要：We characterize the equilibrium behavior in a broad class of competition models in which the competing firms' market shares are given by an attraction model, and the aggregate sales in the industry depend on the aggregate attraction value according to a general function. Each firm's revenues and costs are proportional with its expected sales volume, with a cost rate that depends on the firm's chosen attraction value according to an arbitrary increasing function. Whereas most existing competiti...
